Generalised Anxiety Disorder Assessment (GAD-7)

The Generalised Anxiety Disorder Assessment (GAD-7) is a brief measure for symptoms of anxiety, based on the generalised anxiety disorder diagnostic criteria described in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The GAD-7 assessment asks patients to evaluate their level of symptoms over the last two weeks. When administered on multiple occasion at the start, middle and end of treatment, responses can be used to track treatment progress over time.
